Large department stores and international brands tend to be concentrated around Erqi February 7 Square. The two major department stores are Kingbird éå大 and Beijing Hualien å京åè, which are next to each other. Both stores have supermarkets in their basements.
Some of the most interesting gifts can be purchased at the city's antique market. Most of the shop owners will have a calculator handy so you can bargain by typing in prices. Consider that you got a good deal if you pay half of what they originally quoted. The people are friendly but many of the shops sell fake antiques made to look old. Nevertheless there are interesting items that will decorate your walls or look great on a stand back at home. You can even impress your friends by telling them you bought them an antique from China.
Some of the small shops sell real antiquities. You'll know when you're buying one because the prices will rise dramatically from about ¥100 or less for fake goods to well over ¥5,000 for the real deal.
If you are a collector, China will not let foreigners take antiques out of the country that are over 200 years old or possibly even more recent items depending on their cultural value.
There is a technology market on the south west corner of Dofeng and Wenhua. Most of the items being sold are a little older, but the visit is a great deal of fun, like out of a Gibson novel.
Make sure you know where your wallet is at all times. There are some unsavory characters in the markets. This is, in fact, true of Zhengzhou in general, which has a reputation for pickpockets. Buses are especially risky. Keep your wallet in your front pocket.
